CUTTING TOOL Russian patent published in 2013 - IPC B23C5/20 B23B27/16 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used in cutting tools with mechanical attachment of cutting plates. Cutting tool comprises body with seat accommodating cutting plate. Said plate is secured by the head of L-like clamp with cylindrical guide arranged in body bore and screw fitted in body threaded bore to interact by its end conical surface with that made at L-like clamp cylindrical guide perpendicular to it axis and shifted relative to bore threaded axis. Threaded bore is made in said body perpendicular to L-like clamp cylindrical guide bore. Conical surface of L-like clamp cylindrical guide is shifted toward its head relative to the body threaded bore. Screw conical end surface is offset relative to its axis. Said screw surface offset and clamp cylindrical guide conical surface dependent upon thread pitch and taper angle of both said conical surfaces.

EFFECT: fast replacement of cutting plate.
